Synthetic Studies on Cyclocitrinol: Construction of the ABC Ring System Based on Epoxy-Nitrile Cyclization

The stereoselective synthesis of a model compound containing the ABC ring system of cyclocitrinol was accomplished. After connecting a C ring allyltitanium segment with an A ring bi-cyclo[4.1.0]heptanone segment, the seven-membered B ring moiety was constructed by an intramolecular cyclization reaction of an epoxy nitrile. The enone moiety was introduced through an oxidative decyanation reaction, and the bicyclo[4.4.1]undecane skeleton with the highly strained olefin moiety was formed through a ring-opening reaction of the bicyclo[4.1.0]heptane substructure.

Cycloadditions of Alkenylboronic Derivatives

The literature on cycloaddition reactions of boron-containing alkenes is surveyed with 132 references. The data are categorized according to the reaction type ([2+1], [2+2], [3+2], [4+2], and [4+3] cycloadditions). The cyclopropanation and the Diels-Alder reactions of alkenylboronic derivatives have been studied more or less comprehensively, and for some substrates, they can be considered as convenient methods for the rapid regio- and stereoselective construction of even complex cyclic systems. Other types of the cycloadditions, as well as mechanistic aspects of the processes, have been addressed less thoroughly in the previous works.

Machine learning-based prediction of enzyme substrate scope: Application to bacterial nitrilases

Predicting the range of substrates accepted by an enzyme from its amino acid sequence is challenging. Although sequence- and structure-based annotation approaches are often accurate for predicting broad categories of substrate specificity, they generally cannot predict which specific molecules will be accepted as substrates for a given enzyme, particularly within a class of closely related molecules. Combining targeted experimental activity data with structural modeling, ligand docking, and physicochemical properties of proteins and ligands with various machine learning models provides complementary information that can lead to accurate predictions of substrate scope for related enzymes. Here we describe such an approach that can predict the substrate scope of bacterial nitrilases, which catalyze the hydrolysis of nitrile compounds to the corresponding carboxylic acids and ammonia. Each of the four machine learning models (logistic regression, random forest, gradient-boosted decision trees, and support vector machines) performed similarly (average ROC = 0.9, average accuracy = similar to 82%) for predicting substrate scope for this dataset, although random forest offers some advantages. This approach is intended to be highly modular with respect to physicochemical property calculations and software used for structural modeling and docking.

Nitrile group as IR probe to detect the structure and hydrogen-bond properties of piperidinium/pyrrolidinium based ionic liquids and acetonitrile mixtures

The use of molecular solvents has been proposed as a simple solution to reduce the high viscosities of neat ionic liquids (ILs) and extend the practical applications of ILs. A proper understanding of the structure and intermolecular interaction is of vital importance for the design, optimization and synthesis of ILs systems with tailored properties for specific applications. In this work, the structure and hydrogen-bond features of the representative pyrrolidinium/piperidinium based ILs and acetonitrile mixtures were studied by a combination of Fouriertransform infrared spectroscopy (FTIR) and density functional theory (DFT) calculations. The nu(C N) region is sensitive to the microenvironment and is used as IR probe to detect the structure and hydrogen-bond properties of the two IL-acetonitrile binary systems in the whole concentration range. Positive peaks are observed in the excess IR spectra of nu(C N) region which indicates the non-ideality of the mixing process and the formation of hydrogen-bonded complexes in the mixtures. With the help of deconvolution and DFT calculations, the species transformation in the mixing process can be identified from the excess spectra: When x(CD3CN) is less than 0.90, acetonitrile mainly interacts with the ion pairs and ion clusters of the ILs. Ion clusters are all broken out into ion pairs and the interaction complex is mainly ion pair-CD3CN when x(CD3CN) > 0.90. In the whole concentration range, the CD3CN cannot break apart the strong coulombic interactions between the cation and anion, and the individual cation and anion do not exist in the mixtures. All of the hydrogen-bonds in the ion pair/ion clusteracetonitrile complexes are weak strength, closed shells and electrostatically dominant interactions. (C) 2020 Published by Elsevier B.V.

Poly-2-amino-benzonitrile, a wide dynamic pH linear responding material

In this paper, poly-2-Aminobenzonitrile (PABN), might be thinking as a functionalized polyaniline (PANI), is prepared and its application in the potentiometric pH sensor is demonstrated. The obtained PABN is characterized by FTIR, UV-Vis Spectra, XPS, SEM, BET surface area analysis, and BJH pore size and volume analysis. The pH sensors are characterized by an open circuit potential method with the two-electrode system. The experimental results demonstrate that the potentiometric pH sensors have the near Nernstian sensitivity of -52 mV/pH in the wide range of pH 1 to 13 in phosphate buffers. Prepared pH electrode has significantly lower potential deviation, fluctuation, drift, and hysteresis in sensitivity performances and proved to be the useful one for practical application with long-time stability and repeatability. Ion selectivity tests demonstrate the promising ion-selective electrode of PABN. This idea might be helpful to design functional polymers that have wide range of corresponding properties.

Nickel/Cobalt-Catalyzed Reductive Hydrocyanation of Alkynes with Formamide as the Cyano Source, Dehydrant, Reductant, and Solvent

A Ni/Co co-catalyzed reductive hydrocyanation of various alkynes was developed for the production of saturated nitriles. Hydrocyanic acid is generated in situ from safe and readily available formamide. Formamide played multiple roles as a cyano source, dehydrant, and reductant for the Ni-II pre-catalyst and vinyl nitriles, along with acting as the co-solvent in this reaction. Detailed mechanistic investigation supported a pathway via hydrocyanation of C equivalent to C bond and the subsequent reduction of C=C bond. Wide substrate scope, the employment of a cheap and stable nickel salt as pre-catalyst, a safe cyano source and convenient experimental operation render this hydrocyanation practical for the laboratory synthesis of saturated nitriles.

New Dimensions of Bronsted Base Catalyzed Carbon-Carbon Bond-Forming Reactions

Catalytic carbon-carbon bond-forming reactions of weakly acidic carbon pronucleophiles (pKa in DMSO =30) were developed using strong alkaline metal Bronsted bases as catalysts. Not only weakly acidic amides, esters, nitriles, sulfonamides without any activating group, and alkyl azaarenes, but also alkyl arenes such as toluene, were applicable for the reactions, which are difficult to be applied in typical Bronsted base catalyzed reactions. Expansion to enantioselective reactions was also revealed to be possible. The reactions are atom economical and require only inexpensive alkaline metals rather than precious transition metals. 1 Introduction 2 Catalytic Direct-Type Addition Reactions of Weakly Acidic Carbonyl and Related Pronucleophiles 3 Catalytic Direct-Type Addition Reactions of Alkyl Azaarenes 4 Catalytic Direct-Type Addition Reactions of Alkyl Arenes 5 Conclusion

Recent developments in dehydration of primary amides to nitriles

Dehydration of amides is an efficient, clean and fundamental route for the syntheses of nitriles in organic chemistry. The two imperative functional groups viz., amide and nitrile groups have been extensively discussed in the literature. However the recent development in the century-old dehydration method for the conversion of amides to nitriles has hardly been reported in one place, except a lone review article which dealt with only metal catalysed conversions. The present review provides broad and rapid information on the different methods available for the nitrile synthesis through dehydration of amides. The review article has major focus on (i) non-catalyzed dehydrations using chemical reagents, and (ii) catalyzed dehydrations of amides using transition metal, non-transition metal, organo- and photo-catalysts to form the corresponding nitriles. Also, catalyzed dehydrations in the presence of acetonitrile and silyl compounds as dehydrating agents are highlighted.

Metal-mediated C-CN Bond Activation in Organic Synthesis

Nitriles are ubiquitous versatile building blocks in organic synthesis. Common reactions of nitriles include the transformation of cyano groups into carbonyl and amine moieties. The functionalization of nitriles can also be accomplished at the alpha-position of alkanenitriles and at the ortho-position of cyanoarenes. On the other hand, the C-CN bond of nitriles has rarely been recognized as a valuable reaction site due to its thermodynamic robustness. Although it has been known for a long time in organometallic chemistry that C-CN bonds can be cleaved by transition-metal complexes, this elemental reaction had not been used in catalytic synthetic transformations of nitriles until two decades ago. This review surveys the progress of metal-catalyzed reactions of nitriles via C-CN bond activation. After introducing several different modes to activate C-CN bonds by various transition metals, catalytic reactions are categorized mainly into two parts: (i) reactions with CN as a leaving group and (ii) reactions with nitriles as a source of CN groups. Cross-coupling-type transformations with a cyano leaving group, cyanation reactions using nitriles as a nontoxic cyano source, and novel synthetic reactions such as carbocyanation are highlighted together with useful demonstrations of their utility in organic synthesis.
